HEATING SYSTEM.

Specification of Letters Patent.

Patented July 31, 1917.

Application filed January 9, 1915, Serial No. 1,371. 7 Renewed December19, 1916. Serial No. 137,811.

To all whom. it may concern Be it known that I, CHARLES H. TAYLOR, acitizen of the United States, residing at Oakland, in the county ofAlameda and State of California, have invented certain new and useful.Improvements in Heating Systems, of which the following is aspecification.

This invention relates to improvements in heating systems and morespecifically to a heating system in combination with a domestic hotwater supply. The principal obect of my invention is to produce a clean,safe, economical, and eflicient, dependable system supplying hot waterfor domestic purposes and to a heating system by the use pf a single gasburner and regulator there- Another object is to so construct a systemunder'normal conditions that'the water from the radiators does not passinto the boiler.

Another object of my invention is to allow the water which normallycirculates through the radiators to pass into the boiler when the watersupply therein is heavily drawn upon.

With these and other objects in view my invention consists in the novelconstruction and arrangement of connections as herein described and morespecifically pointed out in the'appended claims.

Reference being had to the accompanying drawing forming a part of thisspecification.

Figure 1 is a view in elevation of my improved boiler and theconnections therefrom to the heating system and domestic water supply.

Fig. 2 is an enlarged sectional view through the lower part of theboiler.

Referring to corres onding parts by the same numerals of ref drence, 1denotes the boiler having the usual inlet and outlet 2 and 3respectively, the outlet 3 being connected with the domestic fixturesone of which is illustrated at 4. The bottom of the boiler is providedwith the recessed portion 5, and extending from the upper portion ofthis recess, through the top of the boiler is a flue 6 by which productsof combustion escape from the cavity 5. Located in this recess are twoheating coils 7 and 8, the former of which is primarily intended forheating the water for the domestic supply and the latter of which undernormal conditions heats the water to the radlator system.

Extending through the center of the bottom 9 and in-threaded engagementtherewith is a special fitting 10 and to the end projecting within theboiler is attached a pipe 11, which extends upwardly and ter- Inmatesadjacent the top of the boiler. The

upper end of this special fitting contains a division wall 12 extendingfrom a point above the bottom 9 to a point below the same. Within theboiler is provided an opening 13 providing a passageway to the interiorof the fitting below the division wall 12. The lower end of coil 7 isconnected to the fitting 10 adjacent its lower end while the upper endof this coil is connected to the fitting adjacent its upper end and onthe opposite side of the division wall 12 from the opening 13. In thismanner a circulation of water is secured from the bottom of the boilerthrough opening 13 down the one side of the division wall 12 through thefitting 10 to the lower end of the 0011 7. As the water becomes heatedit passes upwardly through the coil into the fitting on the oppositeside of division wall 12 and upwardly through pipe 11 into the top ofthe boiler.

Coil 8 has its upper end connected to a pipe 14, which extends upwardlythrough the flue 6, being brought out from the side thereof andconnected by suitable pipes 15 to the radiators 16. The lower end ofcoil 8 is connected by suitable fitting 8 to the side outlet of T 19. Onpipe'l i just below the flue 6 is provided a drip cup 17 so that thewater which condenses on the comparatively cool walls of fine 6 iscaught by this drip pan and is again vaporized and passes oif throughthe flue 14.

In threaded engagement with the lower end of fitting 10 is a shortnipple 18 to which is attached the T 19, and the lower end of the coil 8is connected to the side outlet ofthis T. Below the latter is connecteda second T 20 from the side outlet of which extends pipe 21 to asediment trap or filter 22. The return pipe of the radiators, denoted by23. is attached to the opposite side of the filter, and a thermostaticregulator 25 is connected to'the bottom of the l 20, which has itsthermostatic element 25 extending upwardly into this "5, so as toregulate the temperature of the radiators. 26 denotes the gas supplypipe entering the thermostatic valve and 27 the supply from the valve toa gas burner 28. The recessed lower portion of the boiler is providedwith a door 29 to allow the ready inspection of the coils and burnerwithin the recess, and the whole device is supported on a suitablestructure 30'.

Just outside the top of the boiler pipe 1a and pipe 3 are crossconnected by the nipple 31 and in the usual operation of the system thewater in the boiler circulates as previously described and the waterfrom the radiators circulates upwardly through the coils 8, pipes 14 and15 to the radiators and from the latter through pipe 23 to the filter 22upwardly through the 'ls 20 and 19 to the coil 8.- Under normalconditions little or no flow takes place through the connection 31 orthrough the nipple 18. it, however, a very large amount of water isdrawn 0d from the boiler through one of the domestic fixtures then thewater ascending pipe 1d is hotter than the water which is drawn 0d fromthe boiler, consequently, the hotter water in pipe 1% will flow throughthe connection 31 into pipe 3 and a corresponding amount will flowdownwardly through the nipple 18, T 19 into the bottom of coil 8. Thisin turn operates the thermo stat and allows a greater volume of gas toflow 'therethrough. As the water within the boiler and the radiatorreaches uniform temperature the flow through the nipple 31 and throughthe nipple 18 no longer takes place, and when the water in the boilerand radiators reaches the predetermined temperature the gas is closed edto the amount sufiicient to maintain this temperature.

On the other hand, if no water is drawn through. pipe 3 and the waterwithin the heating system is quickly cooled as when a new radiator isopened, the hot water will fipw from the tank through bypass 31 intopipe 14 and into the radiators. This causes a slower flow through pipe14 below the bypass 31 and consequently the water has time to reach ahigher temperature than otherwise.

supplies water to its respective system, but under abnormal conditionsboth coils are used to heat the colder system.

It will thus be seen that l have provided a system for furnishingdomestic hot water supply and heating radiators from the same unit, thusmaterially reducing the cost oi such installations. and furnishing aneconomical and eiiicient system.

Thus; under normal conditions each coil What 1 claim as new and wish tocover by Letters Patent is 1. A combined hot water supply and heatingsystem comprising in combination, a

reservoir tank, a heating coil, a connection from the lower part of saidtank to the lower part of said coil, a connection from the upper part ofsaid coil to the upper part of said tank, a second heating coil, a riserfrom the upper part of said second coil, one or more radiators connectedto said riser, a return pipe from said radiators to the lower part ofsaid second heating coil, a bypass connecting the lower ends of saidcoils and a second bypass connecting the upper part of said tank to saidriser.

2. A combined hot water supply and heating system comprising incombination, a reservoir tank, an exit pipe leading therefrom, a heatingcoil having its lower part connected to the lower part of the tank andits upper part connected to the upper part of the tank, a second heatingcoil surrounding said first mentioned coil, a riser extending from theupper part of said second heating coil, radiators connected to saidriser, a return from said riser to the lower part of said second coil, abypass between said exit pipe and said riser, a second bypass betweenthe lower ends of said coils and a thermostatic regulator extending intosaid last mentioned bypass.

3. A combined hot water supply and heating system comprising incombination, a reservoir tank having a hollow base, a flueextending fromsaid base through said tank, a heating coil located in said base andprovided with connections from the top and bottom to the top and bottom,respectively, of the said tank, a second coil surrounding said firstmentioned coil, a riser extending through said flue and connected to theupper part of said second mentioned coil, radiators connected to saidriser, a return from said radiators to the lower part of said secondmentioned coil, a water exit pipe extending from the top of said tank, abypass connecting said exit pipe to said riser adjacent said tank, abypass connection between the lower ends of said coils, a burner commonto both of said coils, a gas supply pipe, and a thermostatic valve insaid gas supply pipe, the thermostatic element of said valve extendinginto said last mentioned bypass.
